Declaree Launches Integrated CO₂ Tracking into Expense Management

Finance teams gain transparent, audit-ready data to meet CSRD compliance 

Brussels, 3 September 2025 – Declaree, Mobilexpense’s plug-and-play expense management solution for SMBs and mid-sized companies, launches its integrated  CO₂ tracking capability today.  
 
The new feature enables organisations to calculate, monitor, and report emissions directly from expense data – transforming compliance from a manual burden into a seamless part of everyday workflows. 

EU regulation drives demand for CO₂ reporting 

With the expansion of the EU’s Corporate Sustainability Reporting Directive (CSRD) and European Sustainability Reporting Standards (ESRS), more than 50,000 companies will soon be required to disclose their environmental impact.  

Finance and operations teams face increasing pressure to provide accurate, auditable CO₂ data that goes beyond high-level estimates. 

Integrated carbon tracking in expense workflows 

Declaree’s new capability integrates carbon tracking into existing expense processes without the need for extra tools. Declaree covers all expense types, unlike platforms that export data only consultants are trained to understand. From tracking reimbursements and mileage to invoices, line-item data from receipts and supplier statements delivers a more granular and reliable emissions profile. 

This brings about three major advantages: 

• Transparency: Clear visibility into how each emission is calculated. 
• Compliance: Numbers aligned with CSRD, ESRS, and local ESG mandates. 
• Audit-readiness: Data that can withstand external verification. 
  

Turning reporting requirements into business advantage 

“CFOs should be seeing sustainability as an opportunity to show stakeholders that they are committed to responsible practices instead of a reporting obligation. By embedding emissions data into expense management, Declaree helps finance teams stay compliant today while unlocking insights that actively manage carbon footprints and support cost reduction and efficiency. ” said Salvador Canelas, CPO, Mobilexpense.  

“It’s worth pointing out that if current regulations don’t apply to your company, moving towards carbon neutrality is still essential.” continues Canelas. 

Integrated emissions data allows companies to: 

• Anticipate and meet regulatory requirements. 
• Strengthen credibility with customers, investors, and employees. 
• Identify efficiency opportunities. 
• Incorporate climate impact into financial planning. 

Full traceability for every calculation 

The new CO₂ tracking capability is powered by Lune, a trusted provider of embedded sustainability intelligence whose calculation engine aligns with the Greenhouse Gas (GHG) Protocol, is audited under ISO standards, and continuously updated with globally recognised emissions factors. By embedding this methodology directly into Declaree workflows, companies gain transparent, reporting-ready data with full traceability; every calculation shows the sources, assumptions, and methodology applied.
